Application Notes
Mounting
This chip resistor is ideally suited for handling by automatic
methods due to its rectangular shape and the small
dimensional tolerances. Electrical connection to a ceramic
substrate or to a printed circuit board can be made by wire
bonding to planar terminations or by reflow soldering of
wrap-around terminations. The ‘F’ terminations provide good
leach properties and ensure reliable contact. Due to the
robust construction the resistor chip can be immersed in the
solder bath for 30 seconds at 260°C. This enables the resistor
to be mounted on one side of a printed circuit and wire-
leaded components on the other side. The resistor must be
kept dry during use to avoid leakage. The presence of
moisture will not damage the resistor in any way.
Packaging
Resistor chips are supplied taped and reeled on standard
8mm tape to IEC 286-3.
Quantity per reel 3000 max.
Planar Terminations
Resistor chips are supplied in waffle packs.
